"ANnRAs CSIZMAR, or, DUQUESNE, PENNSYLVANIA;

To all tvhom it may concern v 'Be it known that I, 'Aivnnas- GsrzMAR, a

subject of the King of Hungary, residing at Duquesne in the county of Allegheny and State of. ennsylvania,'have invented certain new and useful Improvements in Rat- Traps, of which the following isa specification, reference being had therein to the accompanying drawing. 7

This. invention relates to rat traps, and has for its object to provide a trap of such class, in .a manner as hereinafter'set forth,

whereby the trap will be automatically re set after the rodent. has been caught and dis charged from a trap compartment. A further object of the inventionis to provide a rodent trap, with means for automatically. supplying bait to theplatform of a trapping compartment, when the platform has been released to discharge .the rodent from said compartment.

scope of theclaims hereunto appended In the drawing wherein like reference characters denote corresponding parts throughoutthe several views: Figure 1 is alongitudinal sectional view of a rattrap in" accordance with this invention. LFig. 2 is a sectional plan. Fig. 3 is an elevation, partly in section, and Fig. 4 is a cross sectional View. y Referring to the drawings in detail, 5 denotes a receptacle containing abody of water 6, and said receptacle 5 is open at its top and further providedwith a continuous inwardly extending supporting flange 7 Mounted upon the-flange 7 is a. casing comprising end walls 9 and 10, and a rear wall 11, a front wall 12,-a bottom plate 13 and a top 14. The casing further includes a partition plate 15, which extends from the top 14 and abuts against the bottom 13. The

rear walill is interposed betweenthe top Specification of Letters Patent.

.14 andbottom 13:,"and is spaced from the partition plate 151.. The rear wall 11 in connection with the partition plate 15, bottom 13 and top :14 formsa chamber 16, and the said .partitionplate 15, topl4, walls 9,

and 10 and shiftableplatform 17' provide a trapping compartment 18. The partition plate 15 is provided with an opening 19 ,for'

establishingv communication between the chamber 16 and the compartment 18. J v

The b0ttom..13,-.-partition plate 15, end

walls 9. and .10 and front wall 12 are mounted upon the flange 7 andthe trapping compartment .18 is mounted [directly over. the open-top of the receptacle 5, whereby when the platform"17 is shifted arodent will be r precipitated therefrom into the receptacle 5 so thattherodent will be drowned in' the Thextop 14 1s formed with an opening 20,

'whichconnnunicates with the trapping compartment 18 and mounted uponthe top 14: is

a receptacle 21, having an. extension 22, which is mounted inthe opening'20, and the said-receptacle 21 contains a liquid bait 22.

The extension22 forms an outlet for the receptacle 2 1, and" said. outlet is normally shut by .a pivoted. spring controlled closure 23,

, the latter being pivoted at 24: to a hanger'25,

which depends from the lower face of the top 14, and said closure 23 includes a downwardly curved arm 26, the latter projecting downwardly from the pivot 24:. -The closure 23 is normally maintained in position to shut the outlet formed by the extension 22, by one end of a spring 26, the latter having its outer end fixedly secured as at 27 to the lower-face of the top 1 1. The spring 26 is permanently in engagement with the closure 23 and. maintains said closure normally in position, shuts the outlet of the receptacle E1 21 and said closure remains in such position untilit is tripped by the .platformg17, in a manner as hereinafter set forth.

The platform -17 at each endthereof is provided with a bearing and the said bear ings are indicated at 28 and 29. Fixed in the end wall 10, is afianged collar 30, in which is journaled a pin 31, the latter extending into the bearing 29, and is fixed thereto as at 32. Fixed into the bearing .28 as at 33, is a spring actuated shaft 34, the latter projecting through a collar 35, fixed in the wall 9, and the said shaft 34: is connected as at 36, to a power transmitting spring 29, the latter being also attached as Y at 28, to the wall 9.' The spring 37 1s inclosed through the medium of a flanged cap 39,the latter being fixed to the outer face of the end walls 9 by the holdfast devices 40.

The shaft 34 projects outwardly from the" cap 39, and has its projecting end squared as at 40 to receive a suitable key for the purpose of winding the spring 37 The function of the spring 37 is to revolve the platform 17 inthedirection of the error 42,.

' and when the platform isrevolved it en'- gages the end 26 of theclosu re 23, and shifts the latter upon'its pivot-whereby a supply of liquid bait 22 "from the receptacle 21 will be had to the platform.

:xThe platform '17 is I normally prevented from revolving by a'latch 43 upon which one side of said platformxseats as illustrated in F ig. 4, andsaid latch 43 includes a resilientshank' 44,,w'hich'is fiiiedxaby. the holdfast'devices 45 tQ'the partition plate 15, and

the said latch and its, shankis arranged atv the opening 19 in the plate 15.

opening 19 isbe veledas at 46 to provide a One wall bracket 50 "projects into the chamber 16.

The outer end of each of the arms 47' and 48 is formed with a right angular lexten'sion 52 in the shape of a loop and the said extensions project through openings 53, inithe: plate 15 and into the compartment 18. A ibgody of bait 54 is carried by each of "the extensions 52, the inner end of each of the arms 47 and 48 is formed with an opening 55and extending through said openings 55 is one end of a .link 56, and the other end ofthe link -56 is attached to an eye 57 projecting from the latch 43.

The front wall 12 is provided With'an entrance opening 58 for the rodent and it will be assumed that the rodent passes through said entrance into the trapplng compartment v 18 and travels upon the platform 17; Un-v less the arms 47 48, or either one of them is or are shifted to release the latch 43, the

platform 17 Will not be shifted through the medium of the weight of the rodent. It will be assumed that the rodent attacks one 05 m of this patent may be obtained for rid-is a pair of oppositely disposed longitudinally ex-,r

ing a liquid baittothe latter is revolved' of the baits 54, pullingthe end 52 ofthev arm 48 inwardly, such action Will shift the latch 53 clear'of the platform 17, thelspring 37. will then come into play and then revolve the platform, and the rodent will be precipi-' tated into the body of water 6. As the platform 17 is revolved it will strike the extension 52of the closure23, rock the same upon its pivot and cause a discharge of the liquid bait upon'the platform .17When the 110- dent .releases -thelbait, thellatch 15'will be:

restored'to normal position and suchhmovea ment of the latchwill be assisted by the Weighted portions .59 ofthe'inner end ofthe holding arms/1:47 and 48. ;The revolving movement of "the platform 17 is "retarded somewhat through the medium of theresiliently supported retarding device 160 carried by the wall 12.

.What I claim is 1. A rat trap comprising a trap compart- 'ment,"a normally locked revoluble spring controlled platform arranged" Within said compartment and forming the bottom there.- of, a latch for normally locking saidplatform, a releasable mechanism actuated by therodent for shifting thelatch to. free said platform whereby the, latter will lee-autosaid platform for revolving itwhen said. latch is shifted to. released position, and means actuated by. said platform for feedplatform when the 2.
